5.3.5 Position control mode (pulse input)
It is required to set the command input pulse form dependent on the upper unit pulse train when using the Position control mode (pulse input).
・ Input form (3 types)
① Forward rotaion pulse train/Reverse rotaion pulse train
② Pulse train/ Directionphase pulse train/B-phase pulse train
③ A-phase pulse train/ B-phase pulse train
・ Logic (2 types)
・ Input form (3 pulse types) × positive/negative logic (2 types) = 6 selectable types
In the upper level device (positioning module), there is a parameter which sets the output pulse form (mode). The form of the upper level device (positioning module) must be made “compatable” with the LECSA. If the forms are not compatable, the operation work correctly. Please be aware that depending on the upper level device
(positioning module), the “command input pulse forms” above may not be available.

① In order to prevent accidental impact at the end of the stroke, operate the actuator at a low speed initially. When changing speed or movement, increase the values whilst checking operation
(Change motorspeed, acceleration/deceleration time, movement distance values if required).
See “LECSA Operation Manual (Simplified Edition)”,section 5.6.2 for motorspeed configuration.
See “LECSA Operation Manual (Simplified Edition)”,section 5.6.3 for acceleration/deceleration time configuration.
See “LECSA Operation Manual (Simplified Edition)”,section 5.6.4 for move distance configuration.
② Actuator positioning operates using [Forward (CCW)] and [Reverse (CW)].
(Check wiring and parameters if operation cannot be performed correctly).
When performing positioning operation in the setup software, the rotation direction of the actuator does not change if you change the setting of parameter PA14 (Rotation direction selection).
The actuator moves in the direction of [Forward (CCW)] button and [Reverse (CW)] button.
③ Check the command impulse unit (electronic gear enabled).
The electronic gear duty set to PA05/PA06/PA07 will be enabled.
See “LECSA Operation Manual (Simplified Edition)”,section 5.3.4 – “Parameter Values by Actuator
Model” for PA05/PA06/PA07 settings for each actuator.
If PA05/PA06/PA07 are set to the values in “LECSA Operation Manual (Simplified Edition)”,section
5.3.4– Parameter Values by Actuator Model, the travel distance of the actuator per 1 pulse will be calculated as follows.
【Position control mode (pulse input)】
・ travel distance of the actuator per 1 pulse = 10[μm] ( 0.01[mm])
【Positioning mode】
・ travel distance of the actuator per 1 pulse = 1[μm] ( 0.001[mm])
④ If the “Stroke-end” (LSP, LSN) signal is not configured as ON, an alarm may occur. (When checked, the “stroke-end” (LSP, LSN) will be automatically turned ON only when this window is open.)

5.6.2 Motorspeed Configuration
<Rotation Speed Configuration>
① Motorspeed (r/min) configuration.
*R/min (rpm): Indicated motor rotation speed (motor rotations/min)
Rotation speed must be between 0 and the allowable speed limit for each actuator. Please be aware that the actuator will not operate if this is set to 0.
If the rotation speed is too low, this may cause vibration; check the actuator while changing settings.
Movement speed (mm/s) must be converted into rotation speed (r/min).
See below for the conversion formula.

5.6.3 Acceleration/deceleration Time Configuation
< Acceleration/deceleration Time Configuration>
① Acceleration/deceleration time (ms) configuration:
The acceleration/deceleration time sets the amount of time (ms) in which a prescribed number of rotations
(3000[r/min]) is reached.
The acceleration/deceleration time must be set to a value between 0 and the allowable acceleration/deceleration speed for each actuator.
The acceleration/deceleration time must be converted from the acceleration/deceleration speed. See below for the conversion formula.
Calculating Acceleration/deceleration conversion example using an actuator with a 8 [mm] lead
with an acceleration of 3000[mm/sec 2 ].
Speed at a rated motor rotation of 3000rpm
Accel/decel time (ms) = {Rated Rotation Speed (r/min) ÷60 (S) }× Screw Lead (mm) × 1000
Acceleration/deceleration speed (mm/s 2 )
Acceleration/deceleration time (ms) = {3000 (r/min) ÷60 (S) } × 8 (mm) × 1000

5.6.4 Move distance Configuration and Operation < Move distance Configuration>
① Set the move distance [pulse]. Select a value within the stroke range.
② Actuator position will operate using [Forward (CCW)], [Reverse (CW)].
The position at which power is turned ON will be set as the home position, and the actuator will travel the amount set as move distance (check wiring and parameters If operation is not performed correctly).
When performing positioning operation in the setup software, the rotation direction of the actuator does not change if you change the setting of parameter PA14 (Rotation direction selection).
The actuator moves in the direction of [Forward (CCW)] button and [Reverse (CW)] button.
③ Check command input pulse units (electronic gear enabled).
The electronic gear duty configured in PA05/PA06/PA07 will be enabled. See “LECSA Operation Manual
(Simplified Edition)”,section 5.3.4 for setting values for PA05/PA06/PA07 in each actuator. If parameters
PA05/PA06/PA07 are set according to“LECSA Operation Manual (Simplified Edition)”,section 5.3.4, the travel distance of the actuator per 1 pulse will be as follows.
【Position control mode (pulse input)】
・ travel distance of the actuator per 1 pulse = 10[μm] ( 0.01[mm])
【Positioning mode】
・ travel distance of the actuator per 1 pulse = 1[μm] ( 0.001[mm])
Travel distance (mm) must be converted to tavel distance (pulse).
See below for the conversion formula. As an example, for a travel of 100m;
【Position control mode (pulse input】
Travel distance of the actuator per 1 pulse = 0.01 (mm)
*1
100 (mm)/0.01 (mm) = 10000 (pulse)
【Positioning mode】
Travel distance of the actuator per 1 pulse = 0.001 (mm)
*1
100 (mm)/0.001 (mm) = 100000 (pulse)
*1 The travel distance of the actuator per 1 pulse is set according to the electronic gears (PA05/PA06/PA07) outlined in 5.3.4 “Recommended
Parameter Values by Actuator Model”.
④ If the stroke end signals (LSP, LSN) are not turned ON, an alarm may occur (If checked, the stroke end
(LSP, LSN) signals will be turned ON automatically only when this window is open).
* Ensure that the [Forward (CCW)] and [Reverse (CW)] driving directions are checked. If the driving direction is unclear, operate the actuator slowly with a small move distance while checking the driving direction.

7.3 Torque control mode
Servo motor output torque is controlled. Speed control function is also available.
* To set [PC**], set parameter write restriction [PA19] to "00E".
7.3.1 Torque Control Mode Operation Instruction
The servo motor will rotate when signal RS1 and RS2 turn on. An operation example of the torque control mode is shown below. Internal torque command settings:
Torque is controlled by the internal torque command set in parameter No. PC12.
If the internal torque command is small, the torque may vary when the actual speed reaches the speed limit value.
In such case, increase the speed limit value.
The following table indicates the torque generation directions determined by the forward rotation selection (RS1) and the reverse rotation selection (RS2) when the internal torque command (parameter No. PC12) is used.
